  4. High Power DC-DC Controllers

    Has anyone looked at design for of high power dc-dc converters to compensate for voltage sag and/or to allow using more batteries in series to reduce the current demands on them? Specifically I would like to use a 1P 180V or higher series string of starter batteries to drive a 144V Curtis...
  5. Idea for AC (or DC) controller

    After considering the idea of a bidirectional DC-DC converter to use perhaps 48 VDC or 96 VDC batteries to provide 240-700 VDC for a VFD, I got the idea that perhaps the DC bus voltage level could be adjusted according to the speed of the motor. My thinking is that, at low speed and high torque...

  8. Regenerative braking with an industrial vfd

    Technical Discussion
    Hello everyone. I am trying to build an electric motorcycle with a Fuji make industrial vfd. This vfd has a DC bus link. The DC link voltage is 600 V. I am planning to use a battery bank of 96 V and will be using a DC-DC converter to step up the voltage from 96 V to 600 V. My question is, if I...

  10. Do I need a DC-DC?

    Batteries and Charging
    Hey guys, I'm in the middle of my 48V Lithium electric motorcycle build and I'm pretty sure that road rules in Australia require a separate battery for the 12V system so you can still run hazard lights etc if the main pack quits. I'm wondering whether you guys think I will need a DC-DC converter...
